I am a router/switch (Cisco) administrator that has been placed in a shop responsible for an enterprise level network. We are running various Windows 2003 server VM's under VMWare ESX 4. I have been asked to determine the resources that need to be monitored and the thresholds that should be set for each resource per server type. (ie exchange, DC, file, SQL, dns, dhcp). We are using Solorwinds for monitoring the network.
I must admit I am a little out of my depth on the systems side of the house. I need recommendations for these thresholds (immediate concern) and/or links to online resources that can quickly educate me on how to design and implement system monitoring for our domain/forest. I could use as many sources as possible as some of them are bound to be blocked by our BlueCoat servers. (Security is high in this desert environment)
